Logging Terms  - R -

RATED CAPACITY: The maximum load a system, vehicle, machine or piece of equipment was designed by the manufacturer to handle.

REACH: A steel tube or wood timber or pole connected to the truck and inserted through a tunnel on the trailer. It steers the trailer when loaded and pulls the trailer when empty.

RECEDING LINE: The line on a skidder or slackline comparable to the haulback line on a yarder.

RELOAD: An area where logs are dumped and reloaded or transferred as a unit to another mode of transportation.

RIGGING CREW: Crew and equipment that drags logs to an area called a deck or landing. From the deck, logs are loaded onto trucks for transport.

RIGGING CUT: The bucking of non-merchantable trees which have been felled or blown down to facilitate easier access to the area by the rigging crew.

RIGGING CUT OR WEAKENING CUT: A tree may be lying in such a position that a normal bucking cut cannot be made safely. In order to facilitate yarding or skidding, the faller will make partial bucking cuts from a safe position, perhaps two log-lengths apart.

ROLLWAY: Any place where logs are dumped and they roll or slide to their resting place.

ROOT PULL: The pulling out of a portion of a tree's root system. Generally a result of not cutting up the corners of the holding wood close enough on a large or heavily leaning tree.

ROOTWAD: The ball of a tree root and dirt that is pulled from the ground when a tree is uprooted.

R.O.P.S.: Roll over protection structure.

RUNAWAY: A tree that has rolled or slid downhill below previously felled and bucked timber.

RUNNING LINE: Any line that moves.

RUSSIAN COUPLING: An incomplete bucking cut as a result of an unsafe bucking situation. In such an instance the faller only partially cuts through the tree. This situation can be very dangerous to the rigging crew. If a Russian coupling is left, the tree should be marked and supervisors notified.
